I am using a library that requires an icon of type package:flutter/src/widgets/icon_data.dart aka IconData. I\'d like to use my own .png file asset as an icon. I googled for solutions and everybody points out to the usage of ImageIcon. However when using this - the following error appears:

        CircularMenuItem(
            iconColor: GuiColors.textLight,
            color: GuiColors.primary,
            icon: ImageIcon(AssetImage(\"assets/icons/sword.png\")),
            onTap: () {
              //callback
            }),

The error is:

The argument type \'ImageIcon\' can\'t be assigned to the parameter type \'IconData?\'. (Documentation)
